Key Features of Outer Planets:
* Large Size: They are significantly larger than the inner rocky planets.
* Gaseous Composition: They are primarily composed of hydrogen and helium.
* Ring Systems: All outer planets have ring systems, with Saturn having the most prominent ones.
* Many Moons: They have numerous natural satellites (moons) orbiting them.
Note: Pluto was once classified as an outer planet but is now considered a dwarf planet due to its size and orbital path.
